HyperLynx SI

HyperLynx® Signal Integrity (SI) performs signal integrity analysis using automated workflows that make advanced analysis accessible to everyday PCB system designers. From pre-route design exploration and “what-if” analysis through detailed verification and sign-off to manufacturing, HyperLynx SI has you covered!

HyperLynx SI supports general-purpose SI, DDR interface signal integrity and timing analysis, power-aware analysis and compliance analysis for popular SerDes protocols, all with the fast, interactive analysis and ease of use and integration HyperLynx is known for. Want to reduce your design cycle and increase your chance of first-pass success with your next high-speed design? Use HyperLynx!

Comprehensive SERDES support

HyperLynx® SI supports frequency-domain, time-domain, Channel Operating Margin (COM) and JCOM analysis for over 35 different popular protocols including the Ethernet, OIF-CEI, PCIe, Fiber-Channel, JESD and USB families.

Integrated full-wave 3D electromagnecic field solver

HyperLynx models key structures in high speed serial links using an integrated 3D solver. For DDR design, an integrated hybrid solver models simultaneous switching noise (SSN) and non-ideal return path behavior for high-speed signals.

Case Studies of PI effects on SI

The interaction between power and signal integrity is often complicated and confusing. With single-ended DDR busses reaching the same data rates as many popular differential SerDes channels, a better understanding of this interaction becomes more crucial. In this paper we discuss some of the primary methods of how power and signal integrity interact with each other, present multiple cases that demonstrate situations where such interactions occur, and offer possible means of mitigation.
